Free Shipping Storewide -Simple Handling fees may apply-

Terra Powersports® has always offered Free Standard Shipping Storewide on any single shipment. We will continue to do so with No Minimums!! Split shipment orders may be subject to an extra charge per shipment made. As usual, our Free Shipping offer does not apply to tires, wheels, chemicals & lubricants, some smaller accessories and oversized items:

* Tires and wheels will still be charged the regular shipping amounts, BUT we have made it possible so that we can waive the extra $7 handling fee that UPS charges!
* Chemicals, lubricants and some smaller accessories do not qualify for this offer.
* Oversized items, like full exhaust systems, will most likely have additional shipping charges added because of the dimensions of the box. If we find that an item is oversized, we will contact you immediately and confirm the new shipping charges before charging you anything. For an explanation of what UPS qualifies as an 'oversized' item, please click here and scroll down to the "Oversize" definition.

The Free Shipping Offer is only offered in the 48 Continental United States. APO/FPO orders do not qualify
